I have this problem. As far as I know there isn't a name for it but if I could make one up it would be "Egeovictusferus" (ee-geo-victus-faar-us) the definition of which would be..."the need to use every food you have access to, even wild ones".
A similar disease, that goes along with this one, is the desire to make/grow everything you need to survive. Seriously, who needs grocery stores?
Yet, the truth of the matter? I mostly eat foods from grocery stores. So I live in a state of... frustration and overweightness.
But! This year I started doing some of the things that I always said I would. Basically, putting all my research to work.
How? By making clover-granola and clover-flour (for bread making) and stir-frying burdock root and cattail shoots.
